To all whom it may concern Be it known that I, LYMAN M. KIANAVEL,

a citizen of the United States, residing at Killbuck, in the county of Holmes and State of Ohio, have invented useful Combination Vrench and Wire- Stretcher; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to the art of combination tool, and an object of the invention is to provide an improved combination wrench and wire stretcher, which comprises particular features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings: Figure 1 is a perspective view of the improved wrench constructed in accordance with the invention showing the stationary jaw of the wrench or tool with its curved portion fulcrumed against a post shown in dotted lines, for stretching the wire. Fig. 2 is, a view partly in side elevation and partly in section, showing the spring 12 in the rectangular boxing 9, and the wheel or roller 16 in section to show the groove 18. Fig. 3 is a sectionalview on line 3-3 of Fig. 2. Fig. 4 is a detail perspective view showing the groove in the wheel or roller and the notch in the stationary jaw omitted.

Referring more especially to the drawings 1 designates the handle end of the wrench, which terminatesat one end in a curved stationary wrench jaw 2, the face 3 of which is provided with teeth 4, arranged in such wise as to maintain a grip upon a pipe to be turned. The toothed face 3 merges into the toothed face of the shank of the stationary jaw the teeth 6 of which are reversely disposed to the teeth of said stationary jaw. The face 7 of the shank between the stationary jaw and the handle end is provided with an elongated groove 8 which gradually merges intothe face 7 A rectangular boxing 9 having a rectangular opening 10 therein is provided. In mounting the boxing 9, the handle end is passed through the rectangular opening until the boxing substantially fits the shank of the stationary jaw, so that the teeth 11 on one face of the rectangular opening cooperate or mesh with the teeth of said shank, so as to hold the A Specification of Letters Patent.

boxing inadjusted positions. A leaf spring.

12, riveted at 13 to one of the inner faces of-the rectangular opening, has its free end riding or engaging the groove 8, and constitutes means to hold the teeth of the boxing and the shank in cooperation. The boxing 9 is provided with a pair of ears 14, in which a pin 15 is mounted. A roller or wheel 16 is movably mounted upon the pin, that is, revolubly mounted, and since the roller is carried by the boxing, the same constitutes a movable jaw, which cooperates with the stationary jaw, for rotating or turning the pipe. By the provision of this form of movable jaw and stationary jaw, intermittent, backward and forward movements may be imparted to the wrench in order to turn the pipe.

Although the wrench embodies features pertaining essentially thereto, it will be seen that the wrench may also be employed as a wire grip and incidentally as a stretcher. For instance in gripping a wire, the wire is arranged so as to engage the groove 16 of the extreme end of the stationary jaw. The end of the wire is passed through the boxing so as to be gripped between the teeth ofthe shank. and the inner teeth of the boxing, in which case the portion a of the wire engages a groove 18 in the roller or wheel, as shown in the drawings. The stationary jaw then fulcrums against the post as shown in dotted lines, and the wrench is swung in the direction of the arrow 6, and owing to the wire being gripped between the cooperating teeth of the shank and boxing, said wire is stretched. The gripping of the wire between said teeth is insured owing to a pull in the direction of the arrow 0 of the portion a of said wire. This pull causes the teeth of the boxing to bury themselves in the wire. In other words the pull causes the portion 19 of the boxing to move in the direction of the arrow (1, thereby gripping the wire.

The invention having been set forth what is claimed as new and useful is A tool comprising a stationary curved of its inner faces provided with teeth to cooperate with the teeth of the shank, means for holding the teeth of the shank and the teeth of the boxing in cooperation said boxing having ears, a wheel journaied between the ears and provided with an annular groove toreceive the wire to be stretched, said wire being designed to be clamped between the teeth of the boxing 10 and the teeth of the shank, boxing adapted to be moved so that the wire may be clamped. between the wheel and the inner curved face of the stationary jaw.

y In testimony whereof I have signed my name to this specification in the presence '15 of two subscribing witnesses.
